I’ve updated both my iPhone 4S and iPad 3rd gen to iOS 7. So far, I both hate it and love it. It’s significantly better on the iPhone than on the iPad.
Let’s just say that on the iPad I’m anxiously looking forward to iOS 7.1, after experiencing several crashes and restarts and an approximate 20% reduction in battery life.
I see this version as a global access to an iOS beta – it’s probably the most unfinished OS version ever launched by Apple. The potential is there, it’s obvious everywhere you look, but… It’s nowhere near the level of polish and flawlessnes we’ve come to expect from Cupertino.
Having said that, I do have high hopes for this new OS. We’ll see how it feels after a couple of updates.
